mold core, side molds, fixing plates, hydraulic cylinder
assemblies, a side mold guide rail, a pressure plate, a bottom
plate, a sprue bush, a lower liquid pressure head, a stamping guide
sleeve, a lower mold, locking modules, a small ejector rod, a small
guide post, guide sleeves and a discharge plate.
[0005] The springs are arranged in the guide posts, the large
ejector rod and the small ejector rod are fixed onto the discharge

into the upper mold fixing plate via the connecting screws, the
locking modules are fixed onto the upper mold fixing plate, the
slanting guide posts are fixed in the cavity formed by the upper
connecting plate and the upper mold fixing plate, the side molds
are combined and separated via the slanting guide posts and the
hydraulic cylinder assemblies, the hydraulic cylinder assemblies
are fixed by the fixing plates to assist in combination and
separation of the side molds, the side mold guide rail is connected
with the pressure plate, the pressure plate is connected with the
lower mold and the bottom plate, and the stamping guide sleeve is
connected with the bottom plate and achieves the effect of guiding
the liquid pressure head.
[0006] The side molds are combined and locked under the action of
resultant force of the slanting guide posts, the locking modules
and the hydraulic cylinder systems, and the problem that a blank
cannot be separated from the mold is solved by a discharge ejector
mechanism composed of the springs, the discharge plate, the large
ejector rod and the small ejector rod.

DETAILED DESCRIPTION
[0037] An improved hub extrusion casting mold includes springs 1,
bolts 2, an upper large plate 3, an ejector rod fixing plate 4,
guide posts 5, an upper connecting plate 6, slanting guide posts 7,
an upper mold fixing plate 7-1, connecting screws 8, a large
ejector rod 9, an upper mold core 10, a blank 11, side molds 12,
fixing plates 13, hydraulic cylinder assemblies 14, a side mold
guide rail 15, a pressure plate 16, a bottom plate 17, a sprue bush
18, a lower liquid pressure head 19, a stamping guide sleeve 19-1,
a lower mold 20, locking modules 20-1, a small ejector rod 21, a
small guide post 22, guide sleeves 22-1 and a discharge plate
23.
[0038] The springs 1 are arranged in the guide posts 5, the large
ejector rod 9 and the small ejector rod 21 are fixed onto the
discharge plate 23 by the ejector rod fixing plate 4, the upper
mold core 10 is fixed into the upper mold fixing plate 7-1 via the
connecting screws 8, the locking modules 20-1 are fixed onto the
upper mold fixing plate 7-1, the slanting guide posts 7 are fixed
in the cavity formed by the upper connecting plate 6 and the upper
mold fixing plate 7-1, the side molds 12 are combined and separated
via the slanting guide posts 7 and the hydraulic cylinder
assemblies 14, the hydraulic cylinder assemblies 14 are fixed by
the fixing plates 13 to assist in combination and separation of the
side molds 12, the side mold guide rail 15 is connected with the
pressure plate 16, the pressure plate 16 is connected with the
lower mold 20 and the bottom plate 17, and the stamping guide
sleeve 19-1 is connected with the bottom plate 17 and achieves the
effect of guiding the liquid pressure head 19.
[0039] During working, the mold is preheated to 300.degree. C.
before working. The molded surface of the hot mold blank on a
machine is coated with a water-based lubricant. Under the drive of
a sliding block of a press, a guide plate and the ejector rod
fixing plate 4 drive the upper mold core 10 to descend and
compress, and simultaneously, the side molds 12 are combined and
locked under the action of resultant force of the slanting guide
posts 7, the locking modules 20-1 and the hydraulic cylinder
systems 14. After smelting, molten liquid magnesium alloy is
injected into the cavity of the magnesium alloy hub extrusion
casting mold via the lower liquid pressure head 19 in the stamping
guide sleeve 19-1, and the molten magnesium alloy is extruded into
a solid blank from liquid rheological punching to crystallization
solidification. The guide plate and the ejector rod fixing plate 4
drive the upper mold core 10 to ascend under the drive of the
sliding block of the press, the side molds 12 are separated under
the action of the slanting guide posts 7 and the hydraulic cylinder
systems 14, and the blank 11 is separated from the lower mold 20
under the action of the lower liquid pressure head 19; after the
blank separation height arrives, an upper ejector rod of the press
acts on the connecting plate 23, and the connecting plate 23 drives
the large ejector rod 9 and the small ejector rod 21 to eject the
blank 11 out of the upper mold core 10 to fall onto the blank tray;
and when the upper ejector rod of the press returns to the upper
position, the discharge plate 23 returns to the upper large plate 3
under the action of the springs 1 to wait next working state.
